Asap!! 85=2x(x^2+3)(2x+5) use quadratic equation

emmainna [20.7K]

Answer:

Step-by-step explanation:

85=2x(x^2+3)(2x+5)

85=2x(2x^3+5x^2+6x+15)

85=4x^4+10x^3+12x^2+30x

4x^4+10x^3+12x^2+30x-85=0

2x^2(2x^2+5x+6)+30x-85=0

shoot, this isn't possible with quadratic, maybe you can get somewhere from here

There are books in a library, there are 4 different kinds of books. Science books make up 3/4 of art books. Comic books are 1/4

Sergeeva-Olga [200]

Answer:

The total number of books is 1020.

Step-by-step explanation:

Denote the books by their first letter.

From the provided information:

$S=\frac{3}{4}A$
$C=\frac{1}{4}T$
$H=\frac{1}{5}T$
$H = A-80$

Compute the expression of T as follows:

$H = A-80\\\\\frac{1}{5}T=A-80\\\\T=5A-400...(i)$

Compute the value of C in terms of A:

$C=\frac{1}{4}T\\\\C=\frac{1}{4}\times {5A-400}\\\\C=\frac{5}{4}A-100...(ii)$

Compute the value of A as follows:

Use expressions (i) and (ii):

$T=S+C+H+A\\\\5A-400=\frac{3}{4}A+\frac{5}{4}A-100+A-80+A\\\\5A-400=4A-180\\\\A=220$

Compute the value of T as follows:

$T=5A-80\\\\T=(5\times 220)-80\\\\T=1100-80\\\\T=1020$

Thus, the total number of books is 1020.

A company ships coffee mugs using boxes in the shape of cubes. The function g(x) = gives the side length, in inches, for a cube

Gekata [30.6K]

Answer:

The graph is attached below.

Step-by-step explanation:

The volume of the box containing the coffee mugs is,

$V=x^{3}$

Then the function representing the side length, in inches, for the box is:

$g(x)=x$

Now, it is provided that the company decides to double the volume of the box.

That is, the new volume will be:

$V_{n}=2x^{3}$

Then the side length, in inches, for the box will be:

$g_{n}(x)=\sqrt[3]{2x^{3}} =\sqrt[3]{2}x$

Then the graph representing the function, formed using the following points is:

$x\ \ \ \ \ \ \ \ \ g_{n}(x)\\\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\\0\ \ \ \ \ \ \ \ \ \ \ 0\\1\ \ \ \ \ \ \ \ \ \ \ 2^{1/3}$
